Square Root is a factor of a number that, when multiplied by itself, gives the original number. This C Program will find squareroot of any number. C language provides **math.h** library file to perform various mathematical operations like square, power.

For example, if we take an example of 25 then the square root is 5.

5*5 = 25

```
// Program for math operations like power, square root.
#include <stdio.h>
#include <math.h>
int main() {
// declaring variable in double
double num,sr;
printf("\nEnter number to find square root\t");
scanf("%lf",&num);
sr = sqrt(num);
printf("\n\nSquare root of number %lf is %lf",num,sr);
return 0;
}
```

**Output**

```
Enter number to find square root 625
Square root of number 625.000000 is 25.000000
```
